Can I make a pen draw a solid line?
There is more than likely a better way to go about this&hellip; but for the time being, it seems this can occur for several reasons, such as how dense your canvas is and the size of the part of the 'brush' touching the canvas etc.

Using the default canvas and brush settings for the most part, you can get around this easily enough by cranking up the number of subdivisions in your canvas mesh and optionally by increasing your Sub-Steps.
